# GoCreative BMR Calculator

> GoCreative BMR Calculator is a paid API for AI agents from api.gocreativeai.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Calculates Basal Metabolic Rate (BMR) given user-supplied physiological parameters via a pay-per-call REST endpoint

## Facts

- Endpoint: GET https://api.gocreativeai.com/v1/calc/bmr/%7Barg%7D
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/gocreative-bmr-calculator-1cef212c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_8dJ4k6DsU7_U3z4mov1OK

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability gocreative-bmr-calculator-1cef212c
```

Example prompt: Can you calculate the basal metabolic rate for a 30-year-old male who is 175 cm tall and weighs 75 kg?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call BMR computation without requiring API keys or signup, especially in agentic workflows that already support x402 micropayments on Base. It is ideal for health, fitness, or nutrition assistants that need resting calorie estimates on demand.

## Known failure modes

- Missing or malformed 'input' query parameter returns a 400 or error response
- Invalid argument format (e.g. non-numeric values where numbers are expected) may cause a computation error
- Payment not included or insufficient USDC on Base triggers a 402 Payment Required response
- Server-side error if argument string cannot be parsed into expected BMR formula inputs

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns a computed BMR value (calories per day at rest) based on the supplied physiological inputs such as age, sex, height, and weight
